1,4-Butanediol glycidyl ether, tseem hu ua 1,4-butanediol dialkyl ether lossis BDG, yog cov organic compound. Nws yog soluble nyob rau hauv feem ntau cov organic solvents xws li ethanol, methanol thiab dimethylformamide.Feem ntau siv los ua tshuaj raw cov ntaub ntawv thiab cov kuab tshuaj. Nws kuj yog siv los ua tus stabilizer rau dyes thiab pigments.Nws tuaj yeem tsim los ntawm esterification ntawm 1,4-butanediol nrog methanol lossis methanol tov. Cov tshuaj tiv thaiv kab mob feem ntau yog nqa tawm nyob rau hauv siab siab thiab nyob rau hauv lub xub ntiag ntawm ib tug catalyst.

Thaum siv 1,4-butanediol glycidyl ether, yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Thaum siv thiab khaws cia, yuav tsum zam qhov kub thiab qhov hluav taws kub. Ua tib zoo mloog rau kev sib khi ntawm cov thawv ntim khoom kom tsis txhob evaporation thiab to.
